Viral Video Contest

Summer Camp Festival is excited to introduce 'The Sh*t SCampers Say video contest. To enter, the event is asking fans to create a 1-3 minute video about 'Sh*t Scampers Say.' The video should follow the same format at the other 'sh*t people say' videos.

Fans then upload the video onto YouTube, and email their video's link to holly@jaytv.com no later than by February 29. Summer Camp will post all of the videos up on its web site, and select the top 10 entries. The voting then lands in the hands of its 40,000 Facebook fans to select their favorite video.

The video with the most votes by March 16 will be named the winner, and receive a 'Super Deluxe VIP' experience for two to the 2012 Summer Camp Music Festival. The next four videos with the most votes receive a 3-day pass to the festival for their hard work and creativity, and all top 10 entries will be shown at the 2012 Summer Camp Music Festival on the big screen. The deadline for entries is midnight on February 29 and all entries must be 100% original.
